Complete Explanation:A patriotic but fanciful portrayal of Union forces marching on the South at the opening of the Civil War. Led by a blue-uniformed officer with a drawn sword, a large troop of men march forward. All are dressed in the large white top hats, striped pantaloons, and jack boots characteristic of Yankee character Brother Jonathan. In the background, to the north, is the Potomac River and, beyond, the Washington skyline with the Capitol building.
